Serum markers of type III and IV procollagen processing predict recurrence of fibrosis in liver transplanted patients.

October 16, 2019

Sci Rep

Abstract Following liver transplantation (LT), 10-30% of patients develop recurrent cirrhosis (RC). There is an urgent need for predictive non-invasive markers for improved monitoring of these patients. Here we studied extracellular matrix biomarkers as predictors of RC after LT. Forty-seven LT patients were divided into groups of fast, intermediate or non-progressors towards RC (5 years […]

Improvement of non-invasive markers of NAFLD from an individualised, web-based exercise program.

October 1, 2019

Aliment Pharmacol Ther

Abstract BACKGROUND Lifestyle modifications remain the cornerstone of treatment in non-alcoholic fatty liver disease (NAFLD). However, they requently fail related to the inability of patients to implement lasting changes. AIMS To evaluate the effects of a short, web-based, individualised exercise program on non-invasive markers of hepatic steatosis, inflammation and fibrosis. METHODS Patients with histologically confirmed […]

Biochemical markers in osteoarthritis with lessons learned from osteoporosis.

October 1, 2019

Clin Exp Rheumatol

Abstract Osteoarthritis (OA) is a disease of the whole joint, including synovium, bone and cartilage. OA is a slow degenerative and very heterogeneous disease, with both varying levels of disease activity and progression. Biomarkers are urgently needed to assist drug developers in selecting and developing the projects with the highest chance of success. Biomarkers for […]

Associations between biomarkers of bone and cartilage turnover, gender, pain categories and radiographic severity in knee osteoarthritis.

September 3, 2019

Arthritis Res Ther

Abstract BACKGROUND Excessive cartilage degradation is a known characteristic of osteoarthritis (OA). Biochemical markers, such as uCTX-II, have been shown to be associated with disease severity, yet the tissue origin of CTX-II has been disputed. This analysis investigates the association between OA knee joints at different radiographic stages and pain categories with levels of uCTX-II […]

Markers of Collagen Formation and Degradation Reflect Renal Function and Predict Adverse Outcomes in Patients With Type 1 Diabetes.

September 1, 2019

Diabetes Care

Abstract OBJECTIVE Patients with type 1 diabetes (T1D) have a higher risk of developing chronic kidney disease, cardiovascular events (CVEs), and mortality than the general population. We hypothesized that two previously published biomarkers, namely PRO-C6, a biomarker of collagen type VI formation, and C3M, a biomarker of collagen type III degradation, may be associated with […]

Serum tau fragments as predictors of death or poor neurological outcome after out-of-hospital cardiac arrest.

September 1, 2019

Biomarkers

Abstract Anoxic brain injury is the primary cause of death after resuscitation from out-of-hospital cardiac arrest (OHCA) and prognostication is challenging. The aim of this study was to evaluate the potential of two fragments of tau as serum biomarkers for neurological outcome. Single-center sub-study of 171 patients included in the Target Temperature Management (TTM) Trial […]

Metabolites of type I, II, III, and IV collagen may serve as markers of disease activity in axial spondyloarthritis.

August 2, 2019

Sci Rep

Abstract Local inflammation in axial spondyloarthritis (axSpA) leads to the release of collagen metabolites from the disease-affected tissue. We investigated whether collagen metabolites were associated with disease activity and could distinguish non-radiographic(nr)-axSpA from ankylosing spondylitis (AS). A total of 193 axSpA patients (nr-axSpA, n = 121 and AS, n = 72) and asymptomatic controls (n = 100) were included. Serum levels […]

Enhanced processing of von Willebrand factor reflects disease severity and discriminates severe portal hypertension in cirrhosis.

August 1, 2019

Eur J Gastroenterol Hepatol

Abstract OBJECTIVES Portal hypertension in cirrhosis is associated with endothelial dysfunction, impaired wound healing, and decreased platelet count. Increased von Willebrand factor (VWF) formation has been suggested as a compensatory mechanism, but the role of VWF processing has not been directly assessed. The aim was to measure the processing of activated VWF (VWF-A) in addition […]

A non-invasive biomarker of type III collagen degradation reflects ischaemia reperfusion injury in rats.

August 1, 2019

Nephrol Dial Transplant

Abstract BACKGROUND Maintenance of kidney function in kidney allografts remains a challenge, as the allograft often progressively develops fibrosis after kidney transplantation. Fibrosis is caused by the accumulation of extracellular matrix proteins like type I and III collagen (COL I and III) that replace the functional tissue. We assessed the concentrations of a neo-epitope fragment […]

Biomarkers of collagen synthesis predict progression in the PROFILE idiopathic pulmonary fibrosis cohort.

July 12, 2019

Respir Res

Abstract Idiopathic pulmonary fibrosis (IPF) is characterised by excessive extracellular matrix (ECM) deposition and remodelling. Measuring this activity provides an opportunity to develop tools capable of identifying individuals at-risk of progression. Longitudinal change in markers of ECM synthesis was assessed in 145 newly-diagnosed individuals with IPF.Serum levels of collagen synthesis neoepitopes, PRO-C3 and PRO-C6 (collagen […]
